Use the welding tools to modify the motor so it is centered on the bicycle pedal’s axle. Before you do this, remove the pedal. Use scaffolding if necessary. Put the motor housing in place by welding a pipe. Make sure the welded material connects the frame section up to the motor housing.
To ensure this homemade wind generator works, double check the motor housing. Make certain the motor is fastened. If it isn’t, the housing will spin along with the axle.

Create the Blades

Get the bottles and secure plastic with the zip ties. Set the spokes so the wheel will spin when the wind blows. Make a cut on the bottle (2 inches) in a spiral manner. Punch a hole and set the zip ties here. Put in another zip tie if there are spaces left.
Make sure about 30% of the wheel is covered with the blades.
Slice the blades so they don’t hit anything when they start spinning. With this homemade wind generator, you can take away the rest of the bike’s components; they are not necessary and will only take up space.

Mounting the Generator

Position the generator high up. Use the scaffolding or ladder if necessary. A pole is the best option. Now set the wires to the power location. You can use batteries. However they can present problems. Number one, they can overcharge. Secondly, it might run the motor and not get a charge.
If you’re going to use batteries, install a heat sinker so it won’t overcharge. If you’re not sure how to set this up on your homemade wind generator, talk to an electrician. Don’t try installing the batteries if you are unsure.

Tips and Warnings

These treadmill motors can be found in a variety of places. Your best bets are the apartments near colleges. These are usually just placed by the dumpster. You can get one there. The Web is also a good place to look for treadmill motors near you.
Be careful when using welding tools and equipment. Follow all the instructions. If you’re not sure how, have a welder shape the pipes for you. Do not stand near the blades when they’re running.
If you are having trouble mounting the generator, have some of your friends help you. This will prove especially useful if you’re going to use the scaffolding.
If the blades move too fast, they might fly off. Double check to make sure they’re installed properly. Wrongly installed blades won’t just fly off; they might shatter and explode.

These homemade wind generators require more work than most DIY projects. However the payoff can be substantial, so it’s worth giving it a try!
